1 0 4M whom it may concern:

Be it known that I, WILLIAM M. llirronnnn, a citizen of the UnitedStates, residing at Louisville, county of Jefferson, and State ofKentucky, have invented certain new and useful Improvements in Rail-Anchors, of which I do declare the following to be a full, clear, andexact description, reference being had to the accompanying drawings,forming a part of this specification.

' My present invention has for its object to provide a simple andefficient construction of rail anchor designed to prevent the creepingof the rails of railway tracks and the invention consists in thefeatures of improvement hereinafter described, illustrated in theaccompanying drawings and particularly de fined in the claims at the endof this speciflcation. By the, term rail anchor, as here employed I wishto have it understood as including notmerely'devices designed to preventthe creep- Figure l is a plan view of a rail anchor embodying myinvention, a portion of a railway rail and of a track tie being alsoshown.

Fig. 2 is a view in cross section on line m'm ofFig. 1. Fig. 3 is an endview of'the rail anchor, the tie being shown in section on line 3-3 ofFig. 1. Fig. 4 is a view in cross sectionon line 4-4 of Fig. 2, aportion of a invention shown in Fig. 6. Fig. 8 is a view similar to Fig.1 but showing an embod1-- ment of my invention as applied to an anti- Icreeper tie plate. Fig. 9 is a view online 99 of Fig. 8. Fig.- 10 is aview on line 10-10 of Fig. 9, the lockingjaw, being omitted.

In the accompanying drawings A designates a railway rail and Bdesignates a rail-- way tie adjacent to which my improved ra1l.

body portion of my improved anchor com prises a member C adapted toextend across and beneath the base flanges a and a of the rail A. At oneend of the member C there is formed a suitable jaw G that is shown asformed integral'with the member C and provided with a slot 0 adapted toreceive the 1 base flange a of the rail. The upper portion of the member0 is arranged to bear against the lower surface of the base of the railand at the side of the member C farthest from the fixed jaw C is formeda shoulder 0' adapted to bear against the outer edge of the base flange(1 of the rail. Upon the end of the member C and outside the shoulder cis formed a rib C having an expanded head 0 adapted to fit within acorresponding' groove formed within a locking jaw D that is movablymountedupon said rib.

By reference to Figs. 1 and 3 of the drawings it will be seen that theend of the member'O, that carries the locking jaw D is eX- tendedtransversely and is provided with a downwardly extending abutment Cadapted to bear against the'railway tie B when the anchor is in positionfor use,

In the form of my invention illustrated in Figs. 1 to 7 of the drawings,the upper surface of the endof the member C that carries the locking jawD is provided outside the rib C with a series of serrations or teeth 0adapted to be engaged by a corresponding series of teeth or serrations dthat are formed upon the under side of the outer portion of. the lockingjaw D, these teeth or serrations 0 and d, by their inter-engagement,serving to hold the locking jaw securely in position and againstaccidental displacement when the locking j aw has been placed in position :for use, as will hereinafter more fully appear. 7 v

By reference to Fig. 1 of the drawings, it will be seen that theshoulder c is arranged transversely of the member C and parallel to theline of the outer edge of the rail base flange 0,, and in the preferredembodiment of my invention the rib C? is inclined toward the shoulder a,this inclination of the rib C serving to causethe locking jaw D to moveinward toward the base flange of therail as the'j aw is forced toposition to clamp and hold the flange of the rail. So also, by

reference to Figs. 3 and 4 of the drawings,

it will be seen that the rib C of the member C is inclined downwardlytoward the abutment C SO that as the jaw D is placed in position for useit will also be moved downwardly into firm bearing against the upperinclined surface of the base flange a of the rail. In other words, theshape and arrangement of the rib C? is suchthat as the locking jaw isforced to position for use it will move both downwardly and inwardlytoward the base flange a of the rail and thus'secure a most effectivegrip upon the railbase, this grip being tightened as the railA tends tocreep in the direction of the arrow, Fig. 1 of the drawings. I

The relative sizes of the rib C and of the groove formed within thelocking jaw D are such that the jaw will slip freely and somewhatloosely upon the rib C and as the locking jaw D is passed over the endof the rib C farthest from the abutment C and is moved toward theabutment, the serrated outer lower portion of the jaw will at first rideover the serration a", but as the inner portion cl of the jaw engagesand bears upon the base flange a of the rail, the

v jaw D will rock slightly in the direction of the arrow, Fig. 2, so asto cause its serrations or teeth (Z to Securely interlock with theserrations or teeth 0 at the outer end of the member C.

In applying my improved rail anchor to a rail, the member C will bepassed beneath the rail and the jaw C will be-tightly forced over thebase flange a of the rail and the shoulder c at the opposite end of themember C of the anchor will be brought to bear against the edge of theflange a of the rail. The locking jaw D will then he slipped over theend of the rib C farthest from the abutment C and will be forced towardthe abutment, the shape and arrangement of the rib C causing the lockingjaw, as it is thus placed in position for use, to move inward anddownward toward the base flange a until the inner portion d of thelocking jaw D is in firm engagement with the upper surface of the baseflange a. When the locking jaw D is thus forced into firm bearingagainst the rail flange a, the interlocking serrations or teeth 03 and 0will serve to securely hold the locking jaw in position. By referencemore particularly to F igf 4 .of the drawings, it will be seen that theshoulder 0' tapers downwardly toward the abutment C of the member C,thus permitting the locking jaw to move downward as it is.

forced to position for use.

In Figs. 6 and 7 of the drawings I have shown a slightly modified formof the invention, in which the locking jaw D is formed with serrationsor teeth d located within the groove of the jaw, these serrations orteeth d being adapted to engage with corresponding serrations 01' teeth0 that are formed upon the rib (l \Vhen the serrations are thus formedupon the jaw and rib respectively, the serrations c and (1,

I hereinbefore described, may be omitted or they can also be used ifdesired. "When the serrations (Z and c are used. the transversedlmenslon of the groove 1n the locking awv A It willbe seen that when myimproved rail anchor is applied to a rail, the shoulder 0 will afford aneffective bearing and grip upon the edge of the base flange a of therail while the opposite base flange is engaged by the jaw C,.and thelocking jaw D will serve to firmly maintain the shoulder c in engagementwith the baseflange a .while the jaw D effectively grips .the uppersurface of the flange a. i

My present invention is adapted for use upon rails of different weightsand sizes.- and if the base of the rail be so narrow that the outer edgeof the flange a does not initially bear against the shoulder 0', thishearing will occur as soon-as a slight rocking action" or shackle actionof the anchor occurs incident to the bearing of the abutment C againstthe: tie B. 4

On Sheet 3 of the drawings I have shown my'invention applied in modifiedform to an anti-creeper tie plate. In this form of invention Cdesignates the body or main member of the tie plate that is providedwith suitable holes 0 by which the plate may be spiked to the tie. Atone end of the body member C is formed a rigid jaw C adapted to engagethe base flange a of the rail A. Upon the upper surface of the bodymembet 0 adjacent the opposite end thereof is formed a shoulder 0'corresponding to the,

shoulder 0 in the form of the invention hereinbefore described, andadapted to bear against the outer edge of the base flange a of the rail.Adjacent the shoulder 0' there are formed on the body member C raisedribs C and C that preferably meet at the center of the body member C Thecontour of each of these ribs C and C- is preferably the same as of therib G hereinbefore described, and each of these ribs C and (1 is adaptedto receive a locking jaw D corresponding in function to the locking jawD hereinbefore described and having formed therein a downwardly opengroove to receive the rib upon which it is mou itcd. In this form of myinvention I have s own each of the locle ing jaws as provided at itsouter side with adapted to enter depressions or serrations -0 formed inthe upper surface of the body 9, to permit the portions or tongues (Z tobe readily bent into the depressions (Z when the locking jaws D havebeen securely forced to position for gripping the rail, as indicated inFigs. 8 and 9 of the drawings. In this form of my invention, as in thathereinbefore described, the ribs C and C are inclined both in verticaland horizontal direction so that' as the locking jaws D are forced inposition for use, they will move inward and downward toward the baseflange a of the rail.

In the form of my invention last described, in which theanchor isprovided with two ribs oppositely 'inclined, the creeping of the railwayrail in either or both directions will be effectively prevented; andwhen the locking jaws are in position for use and the tongues or lateralprojections d are hammered down into the seats or depressions of thebody member 0 all danger of the accidental loosening of the locking jaws-D will be avoided.

I wish it distinctly understood that the details of construction aboveset out may be varied without departing from the scope of the inventionand that features of the invention may be employed without-its adoptionas an entirety.
